Dissipation of solar heat within VFD outdoor enclosures is impacted by the enclosure’s interior and exterior surface color and material.

WEATHERFLO enclosures are NEMA Type 3R compliant, standards which ensure VFD protection in a wide range of harsh outdoor applications including irrigation, pulp and paper, water and wastewater, oil and gas, mining, boring and HVAC. WEATHERFLO also complies with the ASHRAE 90.1-2004 energy code requirement.

Hoffman WEATHERFLO enclosures are weather and corrosion-resistant, protecting industrial motors and controls with heavy-duty aluminum construction and stainless mesh screens on the top and base. This guards against debris and animal entrance, and a reflective white polyester finish reduces solar absorption by 75%.

This VFD Outdoor Enclosure comes pre-assembled for easy setup. Once in place, the enclosure back panel features flexible horizontal or vertical openings for fast operator access to reduce downtime. Hoffman’s WEATHERFLO enclosure provides a complete solution, saving you time and protecting your VFD investment.
